I agree that these questions are so important to the development of the project. Before making a device we need to make sure that we can sell it. Why waste money on a project that we will not make money from. Also need to understand the objectives of the device because if they are not realistic we will put ourselves in a situation where the project will never finish. I think the most important question would be “how realistic is the project” we need to make sure the project can be completed and solve a problem. We do not want to make a device that causes more problems than it solves.
